Arvis

THE MASTADORS: When our rescue partner Washington Health Outreach sent a desperate please from a Washington property with 90+ dogs and several recent litters of Lab Mastiff mixes (aka Mastadors) we had to help. We have taken in 11 and counting.

Animal Information: Meet Arvis, an estimated 3 month old female Labrador Mastiff mix with a gorgeous sleek coat and soulful eyes. She is around 30 lbs and growing. She has no aggressive tendencies toward humans and has lived with a large number of other dogs. We will share more info after she decompresses and we get to know her in foster care.

Foster Profile: Arvis was a little fearful at first but is showing she is resilient and wiling to learn. She loves calm respectful kids and her playful side is coming out. More to come soon!
